3 How will you separate the following Items :-
a) Magnetic substance with non Magnetic substance
b) Mixture of water, salt and sand
c) Sharp from the goals
d) Husk from the grains
e) Salt and water
Answers
a) The use of a bar magnet is one of the simplest and easiest ways of physical separation of magnetic substances from non-magnetic substances. This is done by passing the magnet over the mixture when it will pick the magnetic substance out of the mixture
b) It is easy to separate sand and water by filtering the mixture. Salt can be separated from a solution through evaporation. The water can also be recovered as well as the salt if the water vapour is trapped and cooled to condense the water vapour back into a liquid. This process is called distillation
c) I figured the best way to crush your SMART goal is with an equally witty acronym, hence SHARP. Note: To review a SMART goal is one that is Smart, Measurable, Achievable, Relevant and Time-based
d) Husk is separated from heavier seeds of grain by winnowing. Difference in the size of particles in a mixture is utilised to separate them by the process of sieving and filtration. In a mixture of sand and water, the heavier sand particles settle down at the bottom and the water can be separated by decantation.
e) Simple distillation is a method for separating the solvent from a solution. For example, water can be separated from salt solution by simple distillation. This method works because water has a much lower boiling point than salt. When the solution is heated, the water evaporates.
